HINGE- SPECIFICATION forming part of Letters Patent No. 763,256, datedJune 21, 1904. Application filed November 9, 1903- Serial No. 180.426.(N0 model.)

To all whom it may concern:

.Be it known that I, BENJAMIN F. BURTIS, a citizen of the UnitedStates,residing at Gravesend Beach, in the county of Kings and State ofNew York, have invented certain new and useful Improvements in Hinges,of which the following is a specification.

My invention relates to hinges adapted for general use on doors, gates,window-shutters, &c., but specially designed for outdoor use.

The primary object of the invention is to provide a hinge so constructedthat the hinge members may be easily connected, thus avoiding thedifliculty incidentto hanging windowshutters or outside doors or gates,especially in windy weather.

A further object of the invention is to provide a hinge in which thepivot-pintle will be protected from undue strain, as well as from rustor dirt, thus affording a strong and durable hinge.

The construction of the improvement will be fully described hereinafterin connection with the accompanyingdrawings, which form part of thisspecification, and its novel features will be defined in the appendedclaim.

In the drawings, Figure 1 is a view in perspective of the hinge with itstwo members connected. Fig. 2is a side elevation or edge view of the twohinge members disconnected. Fig. 3 is a perspective view of a modifiedconstruction, the two hinge members being connected; and Fig. 4 is avertical section of one of the hinge members, showing more clearly thedepending guiding-lug thereof.

The reference-numerals 1 and 2 designate two plates or leaves formedwith screw-holes 3. The leaf 1 is formed with an integral web or shank4, having a cylindrical enlargement or projection 5, from which projectsa pintle 6, rounded at its upper end to avoid flat or projecting edgeswhich would obstruct the cap portion of the other hinge member infitting the two members together and to lessen friction and insure theproper centering of the cap and pintle.

The upper portion of the cylindrical projection 5 forms an annularshoulder 7, serving as a seat for the cap of the hinge member 2.

The leaf or plate 2 is formedwith a web or shank 8 and a cylindrical cap9, dome-shaped at its upper end to conform to the rounded up per end ofthe pintle and having at its lower end an annular depending flange 10 tooverlap the upper portion of the cylindrical projection 5 of the member1.

The lower edge of the cap 9 rests upon the annular shoulder 7 of theprojection 5 of the member 1, which affords a continuous extendi edbearing for the cylindrical cap and effectually prevents all lateral orbending strain upon the pintle 6, greatly adding to the ease of movementof the hinge member 2 and the durability of the entire hinge.

From the lower edge of the flange 10, at one side thereof, is adepending lug 11, beveled on its inner side to present an inclinedguidingsurface for the rounded end of the pintle to facilitate theconnection of the hinge members.

As illustrated in Fig. 2, when the two members are connected the annularflange 10 of the cap overlaps the upper end of the cylindricalprojection 5, and thus protects the pintle from rain and snow, as wellas from clog ging by dirt and dust.

The diificulty of alining the socket members of two hinges with thepintle members is well known, and a distinguishing feature of thepresent invention is the avoidance of this annoyance and loss of time byproviding the beveled depending lug 11 on the cap member of the hinge tocontact with the rounded upper end of the pintle and guide it into thecap or socket.

The dome-shaped upper end of the pintle not only facilitates itsinsertion into the cap, but also materially facilitates the turning ofthe cap member thereon, as the friction incident to contacting flatsurfaces is avoided.

As will be apparent from the drawings, the pintle is covered andprotected throughout its length and around and below its point ofjuncture with the projection 5, and the clogging of the hinge or itsdeterioration by dampness and rust are thus prevented.

The modified construction illustrated in Fig. 3 shows a double hinge,one member having two pintles and the other two caps ooacting with thepintles. This form of hinge is desirable for heavy gates and shutters.

1 claim- A hinge, comprising two members, one consisting of a leafhaving a web projecting therefrom, a cylindrical projection from saidWeb, the upper end of which forms an annular shoulder, and a pintleextending upward from said projection and rounded at its upper end; andthe other member consisting of a leaf having a projecting web, adome-shaped cap projecting from the web and having a dependmg annularflange bearing on said shoulder,

and a beveled lug depending from said cap to guide the pintle into thecap, said lug being offset from, and extending below the lower edge orbearing surface of the flange of the cap, and overlapping thecylindrical projection of the pintle member.

In testimony whereof I afiix my signature in presence of two witnesses.

BENJAMIN F. BURTIS.
